New racking system by AEROCOMPACT
No compressive or tensile forces from wind or snow are introduced into the sandwich panels
Austrian expert in PV mounting solutions AEROCOMPACT has developed a new support system for solar power systems on sandwich panels. The patented racking system is the first solution on the market that neither stresses nor damages the panels as it transfers all compressive and tensile forces directly into the roof’s substructure.
At the heart of the racking solution from the COMPACT METAL modular system is the 5.8-meter TR74 support rail, which has been available since August.
With its new racking solution, AEROCOMPACT has solved an industry-wide problem: Until now, installers mostly attached PV systems to sandwich panels by screwing the substructure directly to the top layer of the panels with thin sheet metal screws.
However, the interaction of forces caused by snow and wind can permanently damage the top layer in the long run, leading to leaks, detachment of the outer shell and a resulting “static ambiguity.” Manufacturers of sandwich panels report large-scale damage to building roofs.
With AEROCOMPACT’s new support system, the rail does not rest directly on the roof, but is connected directly to the purlin below with self-drilling support screws. The PV substructure is supported entirely on it. No compressive or tensile forces from wind or snow are introduced into the sandwich panels.
“The span of the 5.8-meter long support rail is unique, and the introduction points can absorb very high forces,” said Marco Rusch from AEROCOMPACT.
